About this kit
6-Inch Lift Kit with M1 Shocks, fitment-checked
Rough Country 53740 is a 6-inch lift kit for 2005-2007 Ford F-250 and F-350 Super Duty 4WD trucks, built around front coils, upgraded radius arms, and M1 monotube shocks. It does not fit dually or diesel-engine models, and the factory rear contact overload springs come off during the build.
This 6-inch lift kit for the 2005-2007 Ford F-250 and F-350 Super Duty 4WD covers XL, XLT, Lariat, King Ranch, and Harley-Davidson Edition trims listed in the fitment section. The box carries a front coil package, two heavy-duty radius arm assemblies with rubber-bushed pivots and an axle-end cam for caster adjustment, a rear add-a-leaf, a 3 inch block and U-bolt set with fabricated blocks, and two pairs of M1 monotube shocks. Bolt-on installation, though the factory rear overload springs must be removed. A downloadable installation guide is available.
